Routing number 091206402 is the official 9-digit ABA routing number registered to NORTHERN STATE BANK at PO BOX 617, ASHLAND, WI 54806. It is registered with the American Bankers Association and the Federal Reserve E-Payments Routing Directory. This number is used exclusively within the US domestic payment system — for ACH transfers, direct deposits, check processing, and domestic wire transfers routed through Fedwire.

How to Read Routing Number 091206402

The 9-digit number 091206402 is structured in three segments: 0912 is the Federal Reserve routing symbol — the first two digits identify the Federal Reserve district and the next two identify the specific Federal Reserve processing office handling NORTHERN STATE BANK's transactions. 0640 is the ABA institution identifier — four digits assigned by the American Bankers Association uniquely to NORTHERN STATE BANK. 2 is the check digit — a single digit calculated from the first eight digits using a weighted sum formula (3-7-1 multipliers). Payment processing systems run this calculation in real time to catch routing number entry errors before any funds move.
